I can send email but as i say, if anyone send me email from like yahoo or gmail or any other, that time its giving me sending fail in my yahoo/gmail mail box. Like my site is: www.indiancarz.com and email is: info@indiancarz.com. When anyone send me mail on this mail ID, i cant receive it.

That eMail addy is a Host Server address, the email received there can or should be able to be read from the Host Domain's mail program. If having problems accessing it or any problems related to it must be quired thru your Host.
